Are You Better At Math Than a 4th (or 10th) Grader? 845
New submitter newslash.formatb points to this Washington Post blog post, which "discusses the National Assessment of Educational Progress test (specifically, the math part). One of the school board members took it and was unable to answer any of the 60 math questions, though he guessed correctly on 10 of them. He then goes on to claim that the math isn't relevant to many people. P.S. — if you want to feel like Einstein, check out some sample questions." Maybe this is mostly about the kind of life skills that are sufficient to succeed in management.

Now I got an A the first time around for GCSE, and then at 18 I pretty much completely screwed up my 'pure' maths part and was only partially rescued by the statistical part. Trying to explain stuff to her made me suddenly realize that the parts I was good at, were the parts that I could visualize.
More than that, it wasn't that I had some mental block on some topics - it was just that I'd never learnt them (or been taught them) properly in the first place. If I spent a bit of time looking at the type of question, rather than the specific question, stuff 'clicks'. I came away with 2 thoughts:
1) If my knowledge is supposed to grow 'like a tree', a whole load of branches got lopped off a long time ago - just felt a little bit sad that I'd spent so long no even noticing that I'd given up. This led to a pub conversation around differentiation/integration - I knew what to do, I knew what the inputs and outputs meant (i.e. I could do the questions) but I'd never understood WHY. I'd always been very sniffy about those who could say only multiply if they'd learnt their times table by rote, but I was doing exactly the same thing, just on a topic a little bit more advanced.
2) Other thing I realized was that I was already doing some operations mentally in exactly the same way as some new technique in her book, that I'd never been taught. I'm unsure that everybody thinks in the same way and other techniques vary, but surely I'd have saved time if I'd been taught it - but then maybe it's the fact that my brain decided to solve them this way, that's made it stick for me.
Take for example the first test (47 x 75) ÷ 25
You can either know that you do the thing in the brackets first, then the thing outside - as you've learnt your rules. But stepping back and looking at it as a whole, it becomes trivial.
47 is a bit of a odd number, I'll leave that for now
I'm multiplying something by 75 and then dividing it by 25. So I'll throw those away and multiply by 3. Leaving me with 47 * 3
ah, 47 again. Well it's close enough to 50. So I'll do 50*3 giving me 150.
Finally time for the correction to my not knowing my 47 times table. I knocked off 3*3 to give me the easy 150, so just need to take the 9 off to give the 141.
I genuinely wonder if everybody else worked that out the same way, but it's now just the way my head works. Bit that annoyed me is that whenever I was taught anything, we were told "how to do it" - maybe education would be better if every teacher has to be able to explain 3 ways of approaching any problem. Better yet, rather than testing the student with the question and just getting a boolean pass/fail - the teacher should ask the pupil around their thought processes when they look at the problem - "talk me through it".
The chances of every coming across that particular question in the real world are practically nil. So the purpose of the question is to test whether the process is present in the pupil - yet maths papers NEVER seem to ask for this. From memory there was the 'show working' marks, but they just tended to dry up after the first mistake was made - and aren't particularly conducive to how I personally think (mental white-board and processing explained verbally).

I think it just boils down to the fact that I firstly try to break the question down (obviously), but break it down into things I can hold easily in my head - and this guides how I choose to break it down. It's not the operations I find hard, it's the variables.
150 fits easily as say 'one visual unit'
141 is harder as just considering that number, I'm mentally holding that not as 141, but (14*10)+1. Everytime time I need to recall that number, there's 3 f'in parts of it to juggle, so I'd like to push these 'hard' variables towards the end of my thought process, so I have to deal with them for the absolutely minimum length of time.
Thinking it through even more, I have 'emotions' towards numbers. If I was just asked which number do I prefer, I'd choose 150 over 141. 150 feels friendly, 141 is a pain in the arse and I wish to spend as little time as possible even thinking about it.

As someone with a masters in maths and PhD in physics, this is the same way I did the calculation. In fact, I suspect it's the way anyone who knows some more advanced maths would do it: What you've effectively done (in maths language) is:
1) Use the associative property of multiplication and its inverse: (AB)C=A(BC).
2) Rewrite the unknown product 47*3 in terms of two known products, by first rewriting 47=50-3, thus (50-3)*3.
3) Expand the bracket: 47*3=50*3-3*3.
Now this is much akin to the 'normal' method used to teach kids, except they always expand their brackets in terms of positive numbers broken up by powers of 10, ie 47=40+7, however from a mathematical standpoint there's no reason not to use any splitting you like, only the expedience of learning a limited number of multiplications.
The true gift of good mathematicians is not only being able to make these thought processes, but properly explain them so that others can too. Far too often maths as it is taught is just a voodoo recipe for performing calculations rather than a well explained, reasoned setup. This is fine for people who merely have to perform the function (much as you don't need to know the workings of an internal combustion engine to drive a car) but if you want to derive a deeper understanding of what's going on its woefully insufficient.

I'd done fine at maths throughout school until mid-way through higher (roughly final year of highschool level) I was suddenly struggling. There were whole sections of the syllabus where I just couldn't see it. There'd be a question and I just couldn't grasp how to get from the info given to the solution required. I failed my mock exam, and not just marginally.
I was a "B maybe A" in all other classes. The teacher was pretty good and everything.
As luck would have it, my dad was friends with an engineer who offered some tutoring. First couple of sessions were straightforward and he said he didn't know what the problem was. He was giving me stuff that was as hard as it gets in the exam and I was able to solve them and explain it, not just following memorised procedures. Next session we came across something I just had no idea. He walked through solving it and one of the steps I was just what? I can't even remember what it was, some concept that once you have it you don't even think about it, like how you can multiply both sides of the equation to simplify. He'd barely started explaining it and I was like ooh - it just clicked.
We abandoned the sessions soon after that because I'd literally gone from being an D/E to a strong B student in but a moment of comprehension. I must have simply been off sick that day or something, and the specific weakness never picked up in marking - perhaps due to rather large class sizes. I suspect that's not the real root though. Mid-way through the year, the classes were shuffled and my desk partner was changed from a friend who I worked well with to someone I didn't know and pretty much didn't work with at all. It was probably about this time my grades began to fall and my friend's grades slipped as bad as mine (he was the other mock fail). But he wasn't as lucky as me, he didn't have a dad with an engineer friend, he failed the finals while I was a couple of points away from an A.

Of course, before you go through all that effort (or any formal evaluation for that matter) you should probably figure out exactly why you want to do the testing in the first place. If the point is to use the evaluation to assist in the learning then maybe time would be better spent by having the students create tests for each other and then go over them together in groups, or something "radical" like that.

At worst, you have to multiply by numbers like 29.
No you don't.
"Last week Maureen earned $288.00 (before taxes) for working 40 hours. This week Maureen worked 29 hours at the same rate of pay. How much did Maureen earn (before taxes) this week?"
Divide 288 by 4 to get $72 for 10 hours. Multiply that by 3 to get 30 hours ($216). If 10 hours is $72, then one hour is $7.20
216 - 7.20 = $208.80
That is why I have an engineering degree from a world class university and this guy is a Teacher.
You don't even need to do the subtraction and second multiplication - $397.24 is clearly too high, Half of 288 is 144 - $203 is too close so it has to be 208.80.

Assuming all questions had four options and the answers were uniformly distributed, then yes, the "expected value" is 15. But, surely you recall that the standard deviation of the binomial distribution is sqrt(60*(1/4)*(3/4)) = sqrt(11.25) = approx 3.35. So to get 10 puts you less than 1.5 stdev from the mean. For normally distributed data (which I would expect the scores for such a test with random answer selection), 68% of the results are within 1 stdev, and 95% are within 2.
So, a score of 10 doesn't seem out of place at all. (And this is all high-school level stats, mind you, sticking to the Probability 101 theme here.)

Summary is very misleading (Score:5, Informative)
First, they cite the wrong exam. This school board member was not complaining about the National Assessment of Educational Progress test, but rather the Florida Comprehensive Assessment Test, or FCAT. (The NAEP test adjusts the skill level of its questions on the fly as you're taking the exam, and returns a score that is percentile-based. I'd actually like to see what this board member scores on the NAEP...it's a very good metric that can be used to measure one's skill level, and is not biased or corrupted by political influence.)
Second, the sample questions are misleading. Not only are they "4th grade" & "8th grade" leveled questions (not the 10th grade exam that this board member was complaining about), but even those questions are not as difficult as you will commonly find on a state exam. If you want to see the types of questions on the FCAT, you can look at the item sampler here. [fldoe.org]
I work in Education up in Minnesota. As you can see on page 13 of this report [mespa.net], there is a downward trend across grade levels in "percent proficiency." While the average joe might conclude that most 3rd grade teachers are fantastic while most 11th grade math teachers need to be fired, the skeptic while (rightfully) question the validity of the test. For example, on that table, you'll see that all the 2011 results are about 10-12% lower than their previous years (except the 11th grade). That's because, in 3rd - 8th grade that year, the state moved to a newer, more difficult exam which emphasizes heavier Algebraic understanding (with completion of Algebra I by 8th grade). Because the standards became more difficult, scores dropped. But the uninformed Joe would just conclude that teachers are getting lazier and use these results as a way to blame schools for not doing their job. (These changes to the standards have not affected the 11th grade yet, but will in two more years.)
I personally coached students for and administered the 11th grade exam last year at my school. The questions on the exam are not simple. Rather than throw traditional skill-based questions at you, the questions are worded in a very complex manner, requiring a deep level of understanding of the skills required to solve the problem in order to recognize which skills are required to solve the problem, much like that FCAT exam I linked to above. This test is not a valid metric of what students know or don't know; I saw one student personally who had no problems with the worksheets I provided him during our coaching sessions, but bombed the exam, not because he was stupid, but because he gets severe test anxiety. Other students told me that they just didn't understand what many of the questions were asking them to calculate.
The upper-level state exams are engineered to fail students, so that schools can be labeled failures. Particular politicians want schools to appear as though they are not doing a good job, to validate the privatization of our educational system. While you hear the expression "raising the bar," what they are really doing is increasing the failure rate. It's absurd what kids are being asked to accomplish; cognitive science has shown that what kindergartners and 1st grade students really should be doing is playing and reading, and we're trying to sit them down and teach them Algebra skills. (If you don't believe me, ask a 1st grade teacher in the state of Minnesota...even 1st grade standards now are engineered to incorporate "Algebraic thinking".) It's downright ludicrous, and it's all a political game.
